Beit known that I, CHARLES JEAN NICOUD, citizen of the Republic of France, residing at 22 Alles de Meillan, in Marseille, in the Republic of France, have invented .certain new and useful Improvements in Picker- VRollers, of which the following isa Aspecification.

This invention relates to picker rollers and its obJect is to provide improved picker rollers for use 1n cardmgsilk waste or other i textiles.

fect 1a tearing action upon Ythe textile, the

chief disadvantage incurred being the doubling of Ientwined fibers which occasions considerable waste in carding.

By means of the present invention this disadvantage is obviated, the sl'ivers for 'carding obtained thereby including no ent-wined or bunched fibers or only la Iminimum thereof.

Referring to the accompanying drawings, illustrating the present invention by way of example,

Figure l is a side view Aof the improved picker device;

Fig. 2 is a ypartial top view thereof; i

Fig. 3 is a side view of one of the pointed 'blades according to the invention;

Fig. 4 is a cross section thereof; and

Fig. 5 is a cross section of a set of blades mounted `on their support.

In place of the usual pointed pickers, pointed blades A, preferably of steel, having each a sharped-edged upper portion, are mounted in a holder B of bronze or other suitable material, secured to a support I( ofl hard wood or the like which is, in turn, secured to the picker drum C by suitable screws F, the blades being rmly heldin position by `means of three bolts L. A number of similar supports K are arranged at suitable intervals on lthe periphery of the 'drum C. Each support K is preferably provided near its rear end with a grooved cross piece or channel O of steel, which extends transversely of the periphery of the drum for a purpose to be described hereafter.

The blades are spaced apart so as to form between them a number of channels m, n, for the reception of the yfibers of textiles operated upon by the points of the blades, the fibers being carried into and deposited in upon 4a the channels without-{intermixing 'or entwi-n- Vvangoccurring between them.

v rll'hen V:the ytorn fibers have thus been ydeposited 4in the channels m, n, so as to lie parallel to the vpointed blades, the rotation vof the :drum is stopped. .Asa certain number of fibers caught by a set of blades may have become attac-hed 4to `blades of the following set 4owing to the rapid:rotation of the .drum .during the ,picking operation, the operatorthenislowly puts the :drum in motion by hand Aand separates the fibers extending from oneset-to another by cutting thelsame byffmeans vof `a 'knife .drawnthrough'the channel O across the periphery yof -the drum.

Beh-ind .each set Iof blades, the dnum car- -ries 1a. pair of supports'E to which .is pivoted Va swinging forlcD'Which, Vduring the `operation of the picker blades, is :retained in its vbackward position, against :the drum, :by means :of ya lock .piece V.

, llhen the groupsoif .fibers engaged by'each 4set of bladeshave :been separated :as described above, t-he fork D is ,swung for Ward. The teeth r of the fork D are adapted -to ,lit exactly into :the channels fn while themecesses umbetween the teeth correspond to :the channels m, so :that lwhen the 1fork is swung :forward its teeth come to rest upon eand :are caused to firmly press jupon the textile fibers in the channels -n while the bers in the channels -m remain exposed.

The operator then raisesl the exposed :fibers by means 'of a lknife and v'he swings them bodily forward, whereupon he rolls them up on a wooden stiok'such as isiusual'ly employed for similar operation-s. AAfter having rolled up the exposed :fibers as far as the Vpoints of the blades, the operator swings the fork D backwardfsoasfto expose .the `fibers in the channels n ,and then =he merely has to :remove the lstick in order to obtain the fslivers intended Vfor combing, said slivers being practically free from entwined or bunched b'ers. Claims-v Picker 4device comprising in combination a picker fdru-m, a set of parallel blades carried by said drum, said blades having l`a sharp point fat fone end, land means connected 1 blades, means for securing said set of blades to the periphery of said drum, and means pivoted to said drum and normally held against the periphery thereof between consecutive sets of blades, said means being adapted to enter the spaces between alternate pairs of adjacent blades.

3. Picker device comprising in combination, a set of parallel pointed blades, a Support for said blades, means for securing said blades to said support, a grooved piece of metal secured to the rear upper edge of said support, a picker drum, and means for attaching said support to said drum.

4;. Picker device comprising in combination, a plurality of sets of pointed blades, supports for said blades, a picker drum, means for attaching said supports to the periphery of said drum, swinging forks arranged one behind each set of blades and adapted, when swung forward, to fit into the spaces between the said blades.

5. Picker device comprising in combination a plurality of sets of parallel pointed blades, supports for said blades, a picker drum, means for attaching said supports to the periphery of said drum, bearings arranged in pairs and secured to the drum behind each set ofblades, and swinging forks mounted to swing in said bearings, said forks having teeth adapted to tit into the channels between the blades and the spacing between the consecutive teeth being substantially equal to that between the consecutive blades.

6. Picker device comprising in combination a set of elongated blades having a sharp point at their forward end and a sharp upper edge throughout their length, a support for said blades, a picker drum, and means for attaching said support to said drum.

7. Picker device comprising in combina,

tion a set of blades having a sharp point at their forward end and a sharp upper edge throughout their length, a metal holder for supporting the front portion of said blades, the arrangement being such that the points of the blades project in front of said holder, a wooden support for supporting the rear portion of said blades, a grooved metal piece secured to, and extending along the rear upper edge of said support, a picker drum, and means for attaching said support to said drum.

8. Picker device comprising in combination a set of blades having a sharp point at their forward end and a sharp upper edge throughout their length, a support adapted to hold said blades slightly spaced apart from and parallel to each other, said support having a metal front portion and a wooden rear portion, means for securing the said blades to the said support, a picker drum and means for attaching the said supports to the periphery of the said picker drum.

9. Picker device comprising in combination a picker drum, a plurality of picker members secured to the periphery of said drum, each of said picker members comprising a set of blades having a sharp point at their forward end and a sharp upper edge throughout their length, and a support adapted to hold said blades spaced apart and parallel to each other, the arrangement being such that the points of the blades project in front of the support, bearings secured to the drums in close proximity to and behind each picker member, swinging forks mounted to swing in said bearings, said swinging forks being adapted to lie fiat against the drum when in their rearward position and engage with their teeth the spaces between the parallel blades when in their forward position, the spacing of the teeth of said forks being substantially equal to that between consecutive blades, and means for locking the said forks in their rearward position.

10. Picker device comprising in combination a picker drum, a plurality of picker members secured to the periphery of said drum, each of said picker members comprising a set of parallel steel blades having a sharp point at their forward end and a sharp upper edge throughout their length, and a support for said blades comprising a front portion of metal, a rear portion of wood and a grooved piece of steel arranged immediately behind the said blades along the rear upper edge of the said wooden portion, the arrangement being such that the points of the blades project in front of the support, bearings secured to the drum in close proximity to and behind each picker member, swinging forks mounted to swing in said bearings, said swinging forks being adapted to lie flat against the drum when in their rearward position and engage with their teeth the spaces between the parallel blades when inV their forward position, the spacing of the teeth of said forks being substantially equal to that between consecutive blades, and means for locking the said forks in their rearward position.

In testimony whereof I aix my signature in presence of two witnesses.
